Proman Stena Bulk, the joint venture between Stena Bulk and Proman, christened Stena Prosperous today during a ceremony at the Marina Bay Cruise Center in Singapore. After the ceremony, the 49,900 DWT IMOIIMeMAX vessel will be bunkered with a 20/80 green/conventional methanol blend, which delivers CO2e savings of 31% compared to the same voyage operated on Very Low Sulphur Fuel Oil (VLSFO), while making additional particulate matter (PM), sulphur oxides (SOx), and nitrogen oxides (NOx) savings.
